The purpose of this study was to identify critical technical points that lead to increased ball speed in a maximal toe kick with no run-up (a 'static kick') in blind football. Six visually impaired male players and eight sighted male players participated in the experiment. All participants wore a blindfold to fully remove visual information and performed the static kick. The motion was captured three-dimensionally using an optical motion analysis system. Our results demonstrated that ball speed, maximum linear velocity of the kicking-side thigh, and maximum angular velocity of the kicking-side shank for the sighted player group were significantly greater than those for the visually impaired player group. The sighted players tended to perform the static kick in a similar motion pattern, which was characterised by a backwards rotation of the torso to adequately extend the kicking-side hip joint during the back-swing phase and a stable posture of the lower torso on the frontal plane during the forward-swing phase. This motion pattern is critical to both acceleration of the kicking-side foot and orientation of the foot for a more precise ball contact position.
本研究旨在确定在无助跑（“静态踢”）的最大触球踢中提高球速的关键技术要点。六名视障男性运动员和八名明眼男性运动员参与了实验。所有参与者都戴上眼罩以完全消除视觉信息，并进行静态踢。运动通过光学运动分析系统进行三维捕捉。我们的结果表明，明眼运动员组的球速、踢腿侧大腿的最大线性速度和踢腿侧小腿的最大角速度均显著大于视障运动员组。明眼运动员倾向于以相似的运动模式进行静态踢，其特征是在背摆阶段通过躯干向后旋转来充分伸展踢腿侧髋关节，以及在前摆阶段下躯干在额状面上保持稳定的姿势。这种运动模式对于踢腿侧脚的加速和更精确的触球位置的脚的定向都很关键。
